我使用 jquery-style-switcher.js来改变某些元素的样式.当我点击页面的颜色样式不会更改,并且在此页面的源代码中,将此classjssError错误level0添加到包含颜色的ul标签.此代码在HTML页面中工作,但在CMS中无效！
我通过chrome调试这个js文件,并了解当这个js文件在一般的html文件运行时：一个事件调用它addClickEvents执行,但在我的网站使用这个模板的网站皮肤：addClickEvents函数不执行.调用addClickEvents的函数是init函数

init: function ($root,config) {
        this.$root = $root;
        this.config = config ? config : {};
        this.setDefaultTheme();
        if(this.defaultTheme) {
            // try cookies
            if (this.config.cookie) {
                this.checkCookie();
            }
            // try hover
            if (this.config.hasPreview) {
                this.addHoverEvents();
            }
            // finally,add click events
            this.addClickEvents();
        } else {
            this.$root.addClass('jssError error level0');
        }
    }

在这个函数(init)中：defaultTheme值是undefined !!!!

为什么defaultTheme是未定义的？如果你能回答这个问题,问题就会解决.

你可以看到template是一般网站.我在皮肤中使用这个模板来进行dotnetnuke7,这个问题出现了.
